[0058] Secondly, this application provides a pool cleaning system, including a pool cleaning robot and a water-removal base station as described in the first aspect. The pool cleaning robot is located in the accommodating space of the towing body, and the water-removal base station is used to tow the pool cleaning robot ashore or send the pool cleaning robot into the pool.

[0059] This application provides a water-removable base station, comprising a base station body and a towing mechanism. The towing mechanism is movably connected to the base station body and is movable relative to the base station body. The towing mechanism has a first position and a second position. The first position is where the towing mechanism is at least partially below the water surface, and the second position is where the towing mechanism is detached from the water surface. The towing mechanism includes a towing body and a movable baffle. The towing body has a accommodating space and an opening communicating with the accommodating space, the accommodating space being used to accommodate a water tank cleaning robot. The movable baffle is movably connected to the towing body and is disposed at the opening of the accommodating space. The movable baffle has a first state and a second state. When the movable baffle is in the first state, the movable baffle closes the opening; when the movable baffle is in the second state, the movable baffle opens the opening. When the pool cleaning robot climbs up the pool wall from the water and moves to the location of the towing mechanism, the movable baffle is in the open position to allow the robot to enter its containment space. After the robot is fully inside, the baffle closes, enabling automatic retrieval and towing of the robot ashore. When the robot needs to perform a cleaning task, the towing mechanism moves relative to the base station, propelling the robot closer to the water surface until it is flush with the pool wall. Then, the baffle opens, allowing the robot to fall into the water, thus achieving automatic entry. This process eliminates the need for manual placement and removal of the robot, and allows for timely removal after the cleaning task is completed. This reduces the risk of reduced lifespan due to prolonged immersion in water, making the robot more convenient to use. Attached Figure Description

Detailed Implementation

[0093] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0094] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0095] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device comprising one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0096] Please refer to Figures 1 and 2. This application proposes an off-water base station 1000 for use with a water pool cleaning robot 200.

[0097] Please refer to Figures 1-4. The water-based base station 1000 includes a towing mechanism 100.

[0098] The towing mechanism 100 has a first position W1 and a second position W2. The first position W1 is a position where the towing mechanism 100 is at least partially below the water surface. The second position W2 is a position where the towing mechanism 100 is detached from the water surface.

[0099] Referring to Figure 1, the first position W1 is the position where the towing mechanism 100 is attached to the pool wall M1, so that the pool cleaning robot 200 can move from the pool wall M1 onto the towing mechanism 100, or get in and out of the pool from the towing mechanism 100. In other embodiments, the first position W1 may be a position where at least a portion of the towing mechanism 100 is below the water surface and not attached to the pool wall M1.

[0100] Referring to Figure 2, the second position W2 is where the towing mechanism 100 is detached from the water surface and positioned on the bank of the pool. In other embodiments, the second position W2 can be any other position where the towing mechanism 100 is detached from the water surface.

[0101] As a further optional feature, as shown in Figures 1-4, the water-based base station 1000 also includes a base station body 300.

[0102] The base station body 300 is fixedly installed on the bank of the pool. The towing mechanism 100 is movably connected to the base station body 300 to bring the pool cleaning robot 200 out of the pool, so that the pool cleaning robot 200 leaves the water surface. In this embodiment, the second position W2 is the position where the towing mechanism 100 leaves the water surface and is located on the base station body 300.

[0103] Please refer to Figures 5 and 6. The towing mechanism 100 includes a towing body 10 and a movable baffle 20.

[0104] Please refer to Figures 5 and 6. The towing body 10 has a accommodating space 10a and an opening 10b communicating with the accommodating space 10a.

[0105] Specifically, please refer to Figures 5 and 6. The towing body 10 includes a first side plate 11, a second side plate 12, a third side plate 13, and a bottom plate 14.

[0106] The first side plate 11 and the third side plate 13 are disposed opposite each other in the width direction. The second side plate 12 is connected between the first side plate 11 and the third side plate 13. The first side plate 11, the second side plate 12 and the third side plate 13 are respectively connected to the three sides of the base plate 14.

[0107] Optionally, referring to Figures 5 and 6, the space formed by the first side plate 11, the second side plate 12, the third side plate 13, and the bottom plate 14 is the accommodating space 10a. The opening 10b is located between the first side plate 11 and the third side plate 13, and opposite to the second side plate 12. The bottom plate 14 forms the bottom wall of the accommodating space 10a. The first side plate 11, the second side plate 12, and the third side plate 13 respectively form the three side walls of the accommodating space 10a. The side of the towing body 10 opposite to the bottom plate 14 can be open.

[0108] The accommodating space 10a is used to house the pool cleaning robot 200.

[0109] The movable baffle 20 is movably connected to the towing body 10. The movable connection includes, but is not limited to, a rotational connection, a sliding connection, or a swing connection.

[0110] The movable baffle 20 is disposed at the opening 10b of the accommodating space 10a. The movable baffle 20 has a first state and a second state. In other words, the movable baffle 20 can move from the first state to the second state, and the movable baffle 20 can also move from the second state to the first state.

[0111] Please refer to Figures 7, 8, and 23. When the movable baffle 20 is in the first state, it closes the opening 10b. At least a portion of the movable baffle 20 is located at the opening 10b, preventing the pool cleaning robot 200 from exiting the receiving space 10a through the opening 10b, thus allowing the pool cleaning robot 200 to move with the towing body 10 to the pool wall M1 or the base station body 300. Furthermore, at least a portion of the movable baffle 20 is located opposite the second side plate 12. The movable baffle 20, the first side plate 11, the second side plate 12, and the third side plate 13 together confine the pool cleaning robot 200 within the receiving space 10a.

[0112] Please refer to Figures 9 and 10. The movable baffle 20 is in an intermediate state between the first state and the second state.

[0113] Please refer to Figures 11, 12, and 25. When the movable baffle 20 is in the second state, the movable baffle 20 opens the opening 10b. The movable baffle 20 is located outside the opening 10b (for example, the movable baffle 20 is housed within the first side plate 11 and the second side plate 12, or is located on the side where the bottom plate 14 is located), allowing the pool cleaning robot 200 to exit the receiving space 10a from the opening 10b or enter the receiving space 10a from the outside through the opening 10b.

[0114] In other words, the movable baffle 20 is provided at the opening 10b of the pool cleaning robot 200 to open or close the opening 10b of the towing body 10. That is, the movable baffle 20 is provided at the opening 10b of the towing body 10, and the movable baffle 20 has a first state and a second state. The first state is the state in which the movable baffle 20 opens the opening 10b, and the second state is the state in which the movable baffle 20 closes the opening 10b.

[0115] For example, after the pool cleaning robot 200 completes its cleaning task at the bottom of the pool, it will move upward along the pool wall M1 to the location of the towing mechanism 100. The movable baffle 20 is in the open opening 10b state, and the pool cleaning robot 200 enters its accommodating space 10a through the opening 10b of the towing mechanism 100. After the pool cleaning robot 200 has completely entered, the movable baffle 20 closes the opening 10b. Then, the towing mechanism 100 moves relative to the base station body 300 to drive the pool cleaning robot 200 to move away from the water surface until the towing mechanism 100 is stacked on the base station body 300, thereby realizing the automatic departure of the pool cleaning robot 200 from the pool. When the pool cleaning robot 200 needs to perform a cleaning task, the towing mechanism 100 moves relative to the base station body 300 to drive the pool cleaning robot 200 towards the water surface until the towing mechanism 100 is in contact with the pool wall M1. Then the movable baffle 20 opens the opening 10b so that the pool cleaning robot 200 falls into the water, thereby realizing the automatic water entry of the pool cleaning robot 200.

[0116] This application provides a water-removable base station 1000, which includes a base station body 300 and a towing mechanism 100. The towing mechanism 100 is connected to the base station body 300 and is movable relative to the base station body 300. The towing mechanism 100 has a first position W1 and a second position W2. The first position W1 is where the towing mechanism 100 is at least partially below the water surface, and the second position W2 is where the towing mechanism 100 is detached from the water surface. The towing mechanism 100 includes a towing body 10 and a movable baffle 20. The towing body 10 has a accommodating space 10a and an opening 10b communicating with the accommodating space 10a. The accommodating space 10a is used to accommodate a pool cleaning robot 200. The movable baffle 20 is movably connected to the towing body 10. The movable baffle 20 is located at the opening 10b of the accommodating space 10a. The movable baffle 20 has a first state and a second state. When the movable baffle 20 is in the first state, the movable baffle 20 closes the opening 10b. When the movable baffle 20 is in the second state, the movable baffle 20 opens the opening 10b. When the pool cleaning robot 200 climbs up the pool wall M1 from the water and moves to the location of the towing mechanism 100, the movable baffle 20 is in the open opening 10b state to allow the pool cleaning robot 200 to enter its accommodating space 10a. After the pool cleaning robot 200 has fully entered, the movable baffle 20 closes the opening 10b to achieve automatic retrieval and towing of the pool cleaning robot 200 ashore. When the pool cleaning robot 200 needs to perform a cleaning task, the towing mechanism 100 moves relative to the base station body 300 to drive the pool cleaning robot 200 towards the water surface until the towing mechanism 100 is in contact with the pool wall M1. Then the movable baffle 20 opens the opening 10b to allow the pool cleaning robot 200 to fall into the water, thereby achieving automatic water entry of the pool cleaning robot 200. The above process eliminates the need to manually submerge and remove the pool cleaning robot 200 from the water. Furthermore, the robot can be removed promptly after completing its cleaning task, reducing the risk of a shortened lifespan due to prolonged immersion in water and making the use of the pool cleaning robot 200 more convenient.

[0117] The movable baffle 20 is movable relative to the towing body 10. For example, it can move from a first state to a second state or from a second state to a first state. The movement of the movable baffle 20 can be driven by, but is not limited to, electrically driving the movable baffle 20 to open or close the opening 10b; or, driving the walking wheel drive of the pool cleaning robot 200 to open or close the opening 10b; or, moving the pool cleaning robot 200 to the location of the trigger component and pressing the trigger component to drive the movable baffle 20 to open or close the opening 10b, etc.

[0118] The following examples illustrate the driving methods for opening or closing the opening 10b of the movable baffle 20. It should be noted that the movable baffle 20 can move by rotating, sliding, or swinging.

[0119] In a first optional embodiment, referring to Figures 13 and 14, the towing mechanism 100 further includes an electric drive assembly 30. The electric drive assembly 30 is connected to the movable baffle 20. The electric drive assembly 30 is used to drive the movable baffle 20 to place the movable baffle 20 in either the first state or the second state.

[0120] In this embodiment, the electric drive assembly 30 drives the movable baffle 20 to move to the first state to close the opening 10b; or the electric drive assembly 30 drives the movable baffle 20 to move to the second state to open the opening 10b. The electric drive control method is relatively simple and has a fast response. It can accurately control the position of the movable baffle 20 to ensure that the opening and closing of the opening 10b is convenient, fast and accurate.

[0121] It should be noted that the electric drive assembly 30 can not only control the movable baffle 20 to be in the first state and the second state, but also to be in an intermediate state between the first state and the second state.

[0122] Optionally, referring to Figures 13 and 14, the electric drive assembly 30 includes a drive member 31 and a transmission member 32. The drive member 31 is disposed on the towing body 10. One end of the transmission member 32 is connected to the drive member 31, and the other end of the transmission member 32 is connected to the movable baffle 20. The transmission member 32 is used to drive the movable baffle 20 to the first state or the second state under the action of the drive member 31.

[0123] In one specific optional embodiment, the driving component 31 includes a drive motor, and the transmission component 32 includes at least one transmission gear or lead screw.

[0124] Specifically, please refer to Figures 13 and 14. The drive motor is installed in the towing body 10, for example, inside the first side plate 11. The transmission component 32 includes a first transmission gear 321 and a second transmission gear 322. The shaft of the first transmission gear 321 is coaxially connected to the output shaft of the drive motor. The second transmission gear 322 is adjacent to and meshes with the first transmission gear 321, and the shaft of the second transmission gear 322 is also rotatably connected to the movable baffle 20. Optionally, the first transmission gear 321 is a motor gear, and the second transmission gear 322 is a shaft gear. Optionally, the gear radius of the second transmission gear 322 is larger than the gear radius of the first transmission gear 321.

[0125] Further optionally, referring to Figures 13 and 14, the movable baffle 20 can rotate relative to the towing body 10 to a first state or a second state. For example, the movable baffle 20 includes a first rotating arm 21, a baffle body 22, and a second rotating arm 23. The second transmission gear 322 can be connected to the first rotating arm 21.

[0126] When the drive motor drives the first transmission gear 321 to rotate, the second transmission gear 322 rotates along with the first transmission gear 321. The second transmission gear 322 drives the first rotating arm 21, the baffle body 22 and the second rotating arm 23 to rotate, thereby causing the movable baffle 20 to rotate to the first state or the second state.

[0127] In this embodiment, the second rotating arm 23 rotates with the first rotating arm 21. In other embodiments, there are two sets of electric drive components 30, which are respectively located on the first side plate 11 and the third side plate 13. The two sets of electric drive components 30 drive the first rotating arm 21 and the second rotating arm 23 respectively, so as to improve the stability of the movable baffle 20 when rotating.

[0128] Optionally, the first rotating arm 21 and the second rotating arm 23 are rotatably connected to the first side plate 11 and the third side plate 13, respectively. Further optionally, the first side plate 11 is provided with at least one limiting member, which is used to limit the rotation position of the first rotating arm 21, thereby limiting the rotation of the movable baffle 20 to the first state or the second state.

[0129] In other embodiments, the movable baffle 20 can also move to the first state or the second state by swinging or sliding.

[0130] Optionally, the transmission component 32 may include, but is not limited to, a lead screw. The drive motor drives the lead screw to move in a straight line, and the other end of the lead screw is connected to the movable baffle 20 to drive the movable baffle 20 to slide to a first state or a second state.

[0131] In other embodiments, the transmission component 32 may also be a conveyor belt, a lead screw and nut, a lead screw and gear, or other structures.

[0132] In other embodiments, the towing mechanism 100 further includes an air source control component and a cylinder.

[0133] Specifically, the air source control component is connected to the cylinder. The air source control component is used to control the extension and retraction of the movable end of the cylinder. The fixed end of the cylinder is connected to the first side plate 11, and the movable end of the cylinder is connected to the movable baffle 20, so as to drive the movable baffle 20 to rotate, slide, or swing to the first state or the second state.

[0134] Optionally, the towing mechanism 100 further includes a sensor and a controller. The sensor is electrically connected to the controller, and the controller is electrically connected to the electric drive assembly 30. The controller is used to control the electric drive assembly 30 when the sensor detects that the pool cleaning robot 200 is about to enter the accommodating space 10a and about to exit the accommodating space 10a, so that the movable baffle 20 is in the second state.

[0135] The controller is used to control the electric drive assembly 30 after the sensor detects that the pool cleaning robot 200 is entering the accommodating space 10a and exiting the accommodating space 10a, so that the movable baffle 20 is in the first state.

[0136] Optionally, the sensor may be located on the towed body 10 or the movable baffle 20. The controller may be located on the towed body 10 or the base station body 300.

[0137] Specifically, the sensor is used to detect whether the pool cleaning robot 200 is in a state of preparing to enter or exiting the accommodating space 10a, and sends the detection result to the controller. Specifically, the sensor includes, but is not limited to, photoelectric sensors, pressure sensors, or Hall effect sensors.

[0138] The controller is used to control the electric drive assembly 30 to move the movable baffle 20 based on the sensor detection results. For example, when the controller detects that the pool cleaning robot 200 has climbed the wall and reached the opening 10b, it controls the electric drive assembly 30 to move the movable baffle 20 to a second state to open the opening 10b. As another example, after the controller detects that the pool cleaning robot 200 has fully entered the receiving space 10a, it controls the electric drive assembly 30 to move the movable baffle 20 to a first state to close the opening 10b, preventing the pool cleaning robot 200 from falling out of the receiving space 10a and facilitating its subsequent towing ashore.

[0139] The controller is used to control the electric drive assembly 30 to move the movable baffle 20 to the second state to open the opening 10b when it detects that the towing body 10 is in the first position W1 and the pool cleaning robot 200 is ready to enter the water.

[0140] In the second optional implementation, please refer to Figures 5, 8, 10 and 12. The movable baffle 20 is driven by the pool cleaning robot 200, so that the movable baffle 20 is in the first state or the second state.

[0141] In this embodiment, the pool cleaning robot 200 and the movable baffle 20 are driven together to move the movable baffle 20 to the first state or the second state, thereby opening or closing the opening 10b. There is no need to set up an electric drive component 31 and a transmission component 32, which reduces the setting of parts and devices and saves energy.

[0142] As a further optional step, please refer to Figures 5, 8, 10 and 12, the pool cleaning robot 200 includes walking wheels 250.

[0143] When the walking wheel 250 contacts the movable baffle 20 and the walking wheel 250 rotates, the movable baffle 20 is in the first state or the second state under the action of the walking wheel 250.

[0144] Optionally, the walking wheel 250 includes a track 210 and a front track wheel 220 and a rear track wheel 230 disposed within the track 210. The front track wheel 220 and the rear track wheel 230 rotate to drive the track 210 to rotate clockwise or counterclockwise, thereby enabling the walking wheel 250 to move forward or backward, and thus enabling the pool cleaning robot 200 to move forward or backward.

[0145] When the track 210 contacts the movable baffle 20 and the track 210 rotates, the movable baffle 20 is in the first state or the second state under the action of the track 210.

[0146] Specifically, referring to Figure 8, when the pool cleaning robot 200 is located within the accommodating space 10a (e.g., about to begin a cleaning task), the movable baffle 20 is in its first state, the opening 10b is closed, and the tail ends of the walking wheels 250 of the pool cleaning robot 200 contact the surface of the movable baffle 20 facing the accommodating space 10a (hereinafter defined as the inner surface of the movable baffle 20). The drive structure of the pool cleaning robot 200 drives the front track wheel 220 and the rear track wheel 230 to rotate, which in turn drives the walking wheels 250 to rotate. During the rotation, the walking wheels 250 drive the movable baffle 20 to rotate along with them through friction. For example, the movable baffle 20 rotates at a certain angle toward the side where the bottom plate 14 is located (pool wall M1). Referring to Figure 10, the pool cleaning robot 200, under the action of the drive structure, passes over the movable baffle 20, exits from the accommodating space 10a, and does not adhere to the pool wall M1 before entering the water. For example, the movable baffle 20 rotates towards the side where the bottom plate 14 is located (pool wall M1) to the second state, as shown in Figure 12. Without the obstruction of the movable baffle 20, the pool cleaning robot 200 exits the accommodating space 10a without contacting the pool wall M1, and then enters the water. After the pool cleaning robot 200 has completely exited the accommodating space 10a, the movable baffle 20 no longer receives force from the pool cleaning robot 200, and the movable baffle 20 can return to the first state under the action of the reset structure.

[0147] Specifically, please refer to Figure 5. When the pool cleaning robot 200 climbs the wall to reach the location of the carrying body 10 (e.g., after completing the cleaning task), if the movable baffle 20 is in the first state and the opening 10b is closed, the front end of the walking wheel 250 of the pool cleaning robot 200 contacts the surface of the movable baffle 20 facing away from the accommodating space 10a (hereinafter defined as the outer surface of the movable baffle 20). The drive structure of the pool cleaning robot 200 drives the front track wheel 220 and the rear track wheel 230 to rotate, which in turn drives the walking wheel 250 to rotate. During the rotation, the walking wheel 250 drives the movable baffle 20 to rotate through friction. For example, the movable baffle 20 rotates at a certain angle toward the side where the bottom plate 14 is located (pool wall M1). Under the action of the drive structure, the pool cleaning robot 200 moves forward and presses down the movable baffle 20 to the second state, so that the opening 10b is fully opened, and enters the accommodating space 10a through the opening 10b. After the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 is no longer subjected to the force of the walking wheel 250, and the movable baffle 20 can be restored to the first state under the action of the reset structure.

[0148] In this embodiment, the front end of the traveling wheel 250 may also refer to the front end of the track 210. In this embodiment, the rear end of the traveling wheel 250 may also refer to the rear end of the track 210.

[0149] Further optionally, referring to Figures 8, 10, and 12, the outer surface of the traveling wheel 250 is provided with a plurality of first protrusions 211. The first protrusions 211 include, but are not limited to, raised dots or raised strips. In this embodiment, the first protrusion 211 is a raised strip. The first protrusions 211 extend along the width direction. In this embodiment, the outer surface of the traveling wheel 250 may also refer to the outer surface of the track 210.

[0150] Please refer to Figures 8, 10, 12, and 15. The movable baffle 20 has a plurality of second protrusions 24 on its surface facing the accommodating space 10a. The second protrusions 24 include, but are not limited to, raised dots or raised strips. In this embodiment, the second protrusions 24 are raised strips. The second protrusions 24 extend along the width direction.

[0151] When the traveling wheel 250 contacts the movable baffle 20 and rolls outward toward the accommodating space 10a, at least a portion of the first protrusion 211 engages with at least a portion of the second protrusion 24. The movable baffle 20 moves from the first state to the second state under the action of the traveling wheel 250.

[0152] Specifically, when the tail end of the traveling wheel 250 contacts the inner surface of the movable baffle 20 and the traveling wheel 250 rolls outward toward the accommodating space 10a, at least a portion of the first protrusion 211 engages with at least a portion of the second protrusion 24 to increase the friction between the traveling wheel 250 and the movable baffle 20, making it easier for the traveling wheel 250 to drive the movable baffle 20 to rotate and open the opening 10b.

[0153] Optionally, referring to Figures 5 and 16, the outer surface of the traveling wheel 250 is provided with a plurality of first protrusions 211. The surface of the movable baffle 20 facing away from the accommodating space 10a is provided with a plurality of third protrusions 25. The third protrusions 25 include, but are not limited to, raised dots or raised strips. In this embodiment, the third protrusion 25 is a raised strip. The third protrusion 25 extends along the width direction. In this embodiment, the outer surface of the traveling wheel 250 may also refer to the outer surface of the track 210.

[0154] When the traveling wheel 250 contacts the movable baffle 20 and rolls toward the accommodating space 10a, at least a portion of the first protrusion 211 engages with at least a portion of the third protrusion 25. The movable baffle 20 moves from the first state to the second state under the action of the traveling wheel 250.

[0155] Specifically, when the front end of the traveling wheel 250 contacts the outer surface of the movable baffle 20 and the traveling wheel 250 rolls toward the accommodating space 10a, at least a portion of the third protrusion 25 engages with at least a portion of the first protrusion 211 to increase the friction between the traveling wheel 250 and the movable baffle 20, making it easier for the traveling wheel 250 to drive the movable baffle 20 to rotate and open the opening 10b.

[0156] Further optionally, the inner surface of the movable baffle 20 may be provided with a second protrusion 24 and the outer surface of the movable baffle 20 may be provided with a third protrusion 25.

[0157] Optionally, referring to Figure 17, the towing mechanism 100 further includes a reset structure 40 connected between the movable baffle 20 and the towing body 10. The reset structure 40 is used to drive the movable baffle 20, which is in the second state, back to the first state.

[0158] Specifically, when the pool cleaning robot 200 enters the accommodating space 10a, the movable baffle 20 is in the second state, and the opening 10b is open. After the pool cleaning robot 200 has fully entered the accommodating space 10a, the reset structure 40 drives the movable baffle 20, which is in the second state, to return to the first state, thereby closing the opening 10b and restraining (limiting) the pool cleaning robot 200 within the accommodating space 10a, preventing the pool cleaning robot 200 from falling out of the accommodating space 10a. This allows the towing mechanism 100 to move relative to the base station body 300 to move the pool cleaning robot 200 away from the water surface until the towing mechanism 100 is stacked on the base station body 300, thereby realizing the automatic removal of the pool cleaning robot 200 from the pool.

[0159] In one optional embodiment, referring to Figure 17, the reset structure 40 includes an elastic element 40a. The elastic element 40a includes, but is not limited to, a spring, a sheet spring, a torsion spring, etc.

[0160] The elastic element 40a undergoes elastic deformation when the movable baffle 20 moves from the first state to the second state. Under the elastic deformation restoring force, the elastic element 40a drives the movable baffle 20 to return from the second state to the first state.

[0161] For example, taking the movable baffle 20, which includes the aforementioned first rotating arm 21, baffle body 22, and second rotating arm 23, the first rotating arm 21 is rotatably connected to the first side plate 11 via a first rotating shaft, and the second rotating arm 23 is rotatably connected to the third side plate 13 via a second rotating shaft. Taking the reset structure 40 as an example, which is a torsion spring.

[0162] The elastic element 40a includes a sleeve portion, a first torsion arm, and a second torsion arm. The first torsion arm and the second torsion arm are respectively connected to opposite sides of the sleeve portion. The sleeve portion is sleeved on the outer periphery of the first rotating shaft. The first torsion arm abuts against the first rotating arm 21 of the movable baffle 20, and the second torsion arm abuts against the first side plate 11.

[0163] Optionally, there are two reset structures 40, which are respectively located between the first rotating arm 21 and the first side plate 11, and between the second rotating arm 23 and the third side plate 13, so as to drive the first rotating arm 21 and the second rotating arm 23 to generate torque force and rotate synchronously under elastic deformation recovery force, thereby improving the stability of the movable baffle 20 during rotation.

[0164] The force exerted by the elastic element 40a keeps the movable baffle 20 in its first state under natural conditions, with the opening 10b closed. When the movable baffle 20 rotates towards the base plate 14 under the action of an external force (e.g., the action of the wheels 250 of the pool cleaning robot 200), the elastic element 40a deforms. When the external force on the movable baffle 20 is removed, the elastic restoring force of the elastic element 40a causes the movable baffle 20 to rotate away from the base plate 14 until it returns to the first state.

[0165] By setting an elastic element 40a as a reset structure 40, the elastic element 40a can assist the rotation of the movable baffle 20 to quickly close the opening, prevent the pool cleaning robot 200 from coming out of the accommodating space 10a, and improve the structural stability of the pool cleaning robot 200 set in the accommodating space 10a.

[0166] Optionally, the number of reset structures 40 is at least one set.

[0167] Please refer to Figures 18 and 19. Each set of reset structures 40 includes a first rotating member 41, a friction band 42, a second rotating member 43, and a rolling member 44. The friction band 42 connects the first rotating member 41 and the second rotating member 43. The second rotating member 43 connects to the rolling member 44. The friction band 42 increases the transmission friction with the first rotating member 41 and the second rotating member 43, reduces slippage, and increases transmission efficiency.

[0168] The first rotating component 41 is connected to one end of the movable baffle 20. Optionally, the first rotating component 41 includes a first rotating gear 411, a second rotating gear 412, and a first rotating wheel 413. The first rotating gear 411 is coaxially connected to the first rotating arm 21. The second rotating gear 412 is coaxially connected to the first rotating wheel 413. Further, the second rotating gear 412 and the first rotating wheel 413 may be integrally formed in the axial direction. The first rotating gear 411 and the second rotating gear 412 mesh. The friction belt 42 includes, but is not limited to, a friction belt. The second rotating component 43 includes, but is not limited to, a second rotating wheel, which is coaxially connected to the rolling component 44.

[0169] The rolling element 44 is disposed in the accommodating space 10a and located on the side opposite to the opening 10b. Further, the rolling element 44 is rotatably mounted on the second side plate 12. Optionally, the rolling element 44 is a roller.

[0170] When the rolling element 44 rolls under the action of the pool cleaning robot 200, it drives the movable baffle 20 to be in the first state or the second state.

[0171] Specifically, when the pool cleaning robot 200 is located in the accommodating space 10a, the front end of the walking wheel 250 contacts the rolling element 44. The walking wheel 250 rotates, causing the rolling element 44 to rotate. The rotation of the rolling element 44 causes the second rotating wheel, friction belt, first rotating wheel 413, and second rotating gear 412 to rotate synchronously, thereby causing the first rotating gear 411 and the first rotating arm 21 of the movable baffle 20 to rotate.

[0172] When the traveling wheel 250 rotates in the first rotation direction, it drives the movable baffle 20 to move to the first state, thereby controlling the closing of the opening 10b. When the traveling wheel 250 rotates in the opposite direction of the first rotation direction, it drives the movable baffle 20 to move to the second state, thereby controlling the opening 10b to open.

[0173] In this embodiment, there is no need to set up a motor structure. By controlling the rotation direction of the walking wheel 250, the movable baffle 20 can be controlled to move to the first state or the second state, and then the opening 10b can be automatically controlled to close or open through transmission.

[0174] Optionally, the number of reset structures 40 is one or two sets. When there are two sets of reset structures 40, the two sets of reset structures 40 are respectively installed on the first side plate 11 and the third side plate 13. The rolling elements 44 of the two sets of reset structures 40 are spaced apart along the width direction. The two rolling elements 44 respectively cooperate with two sets of traveling wheels 250 for transmission.

[0175] In this embodiment, by setting two sets of reset structures 40, a force is applied evenly to both sides of the movable baffle 20, so that the movable baffle 20 rotates smoothly and avoids problems such as jamming during rotation.

[0176] Alternatively, the rolling elements 44 of the two sets of reset structures 40 can be combined into a single roller.

[0177] In a third optional embodiment, the towing mechanism 100 further includes a triggering component (not shown). At least a portion of the triggering component protrudes from the bottom of the accommodating space 10a (i.e., the base plate 14). The triggering component is kinetically connected to the movable baffle 20.

[0178] When the pool cleaning robot 200 moves and squeezes the trigger component, the trigger component moves in a direction perpendicular to the bottom of the accommodating space 10a, causing the movable baffle 20 to move to open and close the opening 10b.

[0179] The triggering component includes a trigger pressing member and a trigger linkage member. A portion of the trigger pressing member protrudes from the base plate 14 near the opening 10b. When the pool cleaning robot 200 moves and squeezes the trigger pressing member, the trigger pressing member can descend under the pressure of the pool cleaning robot 200.

[0180] In one optional embodiment, the trigger linkage includes, but is not limited to, a steel wire rope or a pull rope. The trigger linkage is connected between the trigger pressing member and the movable baffle 20. More specifically, the first rotating arm 21 of the movable baffle 20 is rotatably connected to the first side plate 11, and the trigger linkage is connected to the end of the first rotating arm 21 near the baffle body 22 or to the baffle body 22.

[0181] When the trigger pressing component descends under the pressure of the pool cleaning robot 200, it pulls one end of the trigger linkage component. As the trigger pressing component descends, the other end of the trigger linkage component drives the movable baffle 20 to rotate toward the base plate 14, causing the opening 10b to open.

[0182] Furthermore, after the pool cleaning robot 200 has fully entered or exited the accommodating space 10a, the trigger pressing member is no longer subjected to pressure from the pool cleaning robot 200. Under the action of an elastic structure (e.g., a spring), the trigger pressing member returns to its initial state of protruding from the base plate 14 and releases the trigger linkage, causing the movable baffle 20 to return to its first state. In this embodiment, the aforementioned elastic member 40a may be provided between the first rotating arm 21 of the movable baffle 20 and the first side plate 11.

[0183] In another optional embodiment, the trigger linkage includes, but is not limited to, a rotating linkage. The middle rotating part of the rotating linkage is rotatably connected to the base plate 14, the short arm of the rotating linkage is connected to the trigger pressing member, and the long arm of the rotating linkage is connected to the movable baffle 20.

[0184] After the pool cleaning robot 200 is fully inside the accommodating space 10a, the triggering press can be lowered under the pressure of the pool cleaning robot 200. The triggering press presses down on one end of the short arm of the rotating link, causing the rotating link to rotate, the long arm of the rotating link to rise, and the movable baffle 20 to slide up to close the opening 10b (i.e., in the first state).

[0185] Furthermore, after the pool cleaning robot 200 leaves the accommodating space 10a, the triggering button is no longer subjected to pressure from the pool cleaning robot 200. Under the action of the elastic structure (e.g., spring), the triggering button returns to its initial state of protruding from the base plate 14. The rotating link rotates, the long arm of the rotating link descends, and the movable baffle 20 slides down to open the opening 10b (i.e., in the second state).

[0186] This application does not limit the movement mode of the movable baffle 20 from the first state to the second state. The following examples illustrate the movement mode of the movable baffle 20 from the first state to the second state.

[0187] In a first optional embodiment, the movable baffle 20 is rotatably connected to the towing body 10. The movable baffle 20 rotates to either the first state or the second state.

[0188] Specifically, please refer to Figure 15. The movable baffle 20 includes a first rotating arm 21, a baffle body 22, and a second rotating arm 23 connected in sequence.

[0189] Please refer to Figures 7-12. The first rotating arm 21 and the second rotating arm 23 are respectively rotatably connected to two opposite side plates of the towing body 10. Optionally, the first rotating arm 21 is rotatably connected to the first side plate 11, and the second rotating arm 23 is rotatably connected to the third side plate.

[0190] The two ends of the baffle body 22 are bent and connected to the first rotating arm 21 and the second rotating arm 23, respectively. The baffle body 22 is arranged along the width direction.

[0191] When the movable baffle 20 is in the first state, the baffle body 22 blocks the opening 10b. Optionally, the first rotating arm 21 is parallel to the base plate 14, or has a relatively large acute angle, or a relatively small obtuse angle.

[0192] When the movable baffle 20 is in the second state, the baffle body 22 is located on the side where the base plate 14 of the towing body 10 is located. Optionally, the first rotating arm 21 is perpendicular or nearly perpendicular to the base plate 14. The baffle body 22 may be flush with the base plate 14, or the surface of the baffle body 22 may be lower than the surface of the base plate 14.

[0193] The methods of driving the movable baffle 20 to rotate include, but are not limited to, the aforementioned electric drive component 30 driving, or the friction drive between the traveling wheel 250 and the movable baffle 20, or the friction linkage between the traveling wheel 250 and the rolling element 44, thereby driving the movable baffle 20 to rotate, or the trigger component driving the movable baffle 20 to rotate, etc.

[0194] In a second optional implementation, as shown in Figures 20 to 22, the movable baffle 20 is slidably connected to the towing body 10. The movable baffle 20 can slide to either the first state or the second state.

[0195] Specifically, please refer to Figures 20 to 22, where there are two movable baffles 20.

[0196] Please refer to Figures 20 and 22. The two movable baffles 20 are respectively disposed on two opposite side plates of the towing body 10. For example, the first movable baffle 20a is disposed on the first side plate 11, and the second movable baffle 20b is disposed on the third side plate 13.

[0197] Each of the movable baffles 20 is slidably connected to the side plate of the towing body 10.

[0198] Referring to Figure 20, when the movable baffle 20 is in the first state, at least a portion of the movable baffle 20 protrudes from the side plate. Referring to Figure 22, when the movable baffle 20 is in the second state, the movable baffle 20 slides and retracts into the side plate.

[0199] Specifically, the first side plate 11 has a first chamber (not shown). For example, a first movable baffle 20a is slidably connected to the first side plate 11. A first elastic mechanism (not shown) is provided between the first movable baffle 20a and the chamber wall of the first chamber.

[0200] Please refer to Figure 20. In the first state, under the action of the first elastic mechanism, a portion of the first movable baffle 20a protrudes from the first side plate 11, and the other portion is located in the first chamber and abuts against the chamber wall of the first chamber, so that the first movable baffle 20a remains relatively stable.

[0201] Referring to Figure 22, the first movable baffle 20a retracts into the first chamber under the compressive force from the first side plate 11 perpendicular to it. At this time, the first movable baffle 20a is in the second state, and the opening 10b is in the open state. After the compressive force is removed, the first movable baffle 20a returns to the first state under the action of the first elastic mechanism, and the opening 10b is in the closed state.

[0202] Correspondingly, the third side plate 13 has a second chamber. For example, a second movable baffle 20b is slidably connected to the third side plate 13. A second elastic mechanism is provided between the second movable baffle 20b and the chamber wall of the second chamber. In the first state, under the action of the second elastic mechanism, a portion of the second movable baffle 20b protrudes from the third side plate 13, and another portion is located inside the second chamber and abuts against the chamber wall of the second chamber, so that the second movable baffle 20b remains relatively stable.

[0203] The second movable baffle 20b retracts into the second chamber under the extrusion force from the perpendicular side plate 13. At this time, the second movable baffle 20b is in the second state, and the opening 10b is in the open state. After the extrusion force is removed, the second movable baffle 20b returns to the first state under the action of the second elastic mechanism, and the opening 10b is in the closed state.

[0204] Further optionally, referring to Figures 20 and 22, the movable baffle 20 (first movable baffle 20a and / or second movable baffle 20b) includes a blocking surface 204 facing the accommodating space 10a and a sliding guide surface 205 facing away from the accommodating space 10a. Taking the first movable baffle 20a as an example, in the first state, the blocking surface 204 is perpendicular or nearly perpendicular to the first side plate 11.

[0205] The sliding guide surface 205 is inclined relative to the blocking surface 204. Optionally, the sliding guide surface 205 can be a plane or an arc surface. Furthermore, the end of the sliding guide surface 205 near the blocking surface 204 is relatively far from the first side plate 11, while the end of the sliding guide surface 205 far from the blocking surface 204 is close to the first side plate 11. In other words, the movable baffle 20 has a wedge-shaped structure, a triangular block structure, etc.

[0206] When the pool cleaning robot 200 abuts against the sliding guide surface 205 and moves toward the accommodating space 10a, since the sliding guide surface 205 is an inclined surface, the pool cleaning robot 200 abuts against the sliding guide surface 205 and forms a force perpendicular to the first side plate 11, which compresses the first elastic mechanism. The movable baffle 20 moves to the second state under the compression of the pool cleaning robot 200, and the opening 10b is in the open state so that the pool cleaning robot 200 can enter the accommodating space 10a.

[0207] After the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 is restored to the first state under the action of the reset structure 40 (first elastic mechanism or second elastic mechanism), and the opening 10b is in the closed state.

[0208] When the opening 10b is closed, and the pool cleaning robot 200 abuts against the blocking surface 204, since the blocking surface 204 is nearly perpendicular to the first side plate 11, the pool cleaning robot 200 will not generate a force perpendicular to the first side plate 11 when it abuts against the sliding guide surface 205. Therefore, the movable baffle 20 is in the first state to support the tail end of the pool cleaning robot 200 and prevent the pool cleaning robot 200 from falling out of the accommodating space 10a.

[0209] The above description of the movable baffle 20 is based on the first movable baffle 20a. The structure of the second movable baffle 20b and its cooperation with the pool cleaning robot 200 can be found in the relevant description of the first movable baffle 20a.

[0210] Further optionally, referring to Figures 20 and 22, the movable baffle 20 also includes a roller 203. The roller shaft of the roller 203 is arranged along the height direction of the first side plate 11. The roller 203 can rotate freely around the roller shaft. The roller 203 is located at the end where the sliding guide surface 205 intersects with the blocking surface 204.

[0211] In this embodiment, a roller 203 is provided at the end of the movable baffle 20. During the process of the pool cleaning robot 200 entering the accommodating space 10a, the roller 203 can roll relative to the side of the pool cleaning robot 200 to reduce the forward resistance of the pool cleaning robot 200 and enable the pool cleaning robot 200 to enter the accommodating space 10a more smoothly.

[0212] In a third optional embodiment, the movable baffle 20 is oscillatingly connected to the towing body 10. The movable baffle 20 oscillates to either the first state or the second state.

[0213] Optionally, the towing mechanism 100 further includes a swing shaft (not shown) and a reset structure (not shown). The swing shaft is disposed on the side plate of the towing body 10 along a first direction. The first direction is the aforementioned height direction.

[0214] One end of the movable baffle 20 is rotatably connected to the swing shaft, and the other end of the movable baffle 20 swings around the swing shaft to either the first state protruding from the side plate or the second state contained within the side plate. The elastic mechanism is disposed within the side plate of the towing body 10 and elastically abuts against the movable baffle 20. The elastic mechanism is used to return the movable baffle 20 to the first state.

[0215] Specifically, the side plate has a chamber. A swing shaft is fixed within the chamber along a first direction. For example, the movable baffle 20 has a wedge-shaped structure, with one end rotatably connected to the swing shaft. An elastic mechanism is provided between the movable baffle 20 and the chamber wall. In the first state, under the action of the elastic mechanism, a portion of the movable baffle 20 protrudes from the side plate, while the other portion lies within the chamber and abuts against the chamber wall, keeping the movable baffle 20 relatively stable.

[0216] The movable baffle 20 can swing (rotate) relative to the swing axis to retract into the chamber under the extrusion force from the side plate perpendicular to it. At this time, the movable baffle 20 is in the second state and the opening 10b is in the open state. After the extrusion force is removed, the movable baffle 20 swings (rotates) in the opposite direction relative to the swing axis under the action of the elastic mechanism to return to the first state and the opening 10b is in the closed state.

[0217] Further optionally, referring to Figures 20 to 22, the movable baffle 20 includes a blocking surface 204 facing the accommodating space 10a and a sliding guide surface 205 facing away from the accommodating space 10a. In the first state, the blocking surface 204 is perpendicular or nearly perpendicular to the first side plate 11.

[0218] In the first state, the sliding guide surface 205 is inclined relative to the blocking surface 204. Further optionally, the sliding guide surface 205 can be a plane or an arc surface. Further, the end of the sliding guide surface 205 near the blocking surface 204 is relatively far from the first side plate 11, and the end of the sliding guide surface 205 far from the blocking surface 204 is close to the first side plate 11. In other words, the movable baffle 20 has a wedge-shaped structure, a triangular block structure, etc.

[0219] When the pool cleaning robot 200 abuts against the sliding guide surface 205 and moves toward the accommodating space 10a, since the sliding guide surface 205 is an inclined surface, the pool cleaning robot 200 abuts against the sliding guide surface 205 and forms a force perpendicular to the first side plate 11, which compresses the first elastic mechanism. Under the compression of the pool cleaning robot 200, the movable baffle 20 swings around the swing axis to the second state, and the opening 10b is in the open state so that the pool cleaning robot 200 can enter the accommodating space 10a.

[0220] After the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 returns to the first state under the action of the elastic mechanism, and the opening 10b is in the closed state.

[0221] When the opening 10b is closed, and the pool cleaning robot 200 abuts against the blocking surface 204, since the blocking surface 204 is nearly perpendicular to the first side plate 11, the pool cleaning robot 200 will not generate a force perpendicular to the first side plate 11 when it abuts against the sliding guide surface 205. Therefore, the movable baffle 20 is in the first state to support the tail end of the pool cleaning robot 200 and prevent the pool cleaning robot 200 from falling out of the accommodating space 10a.

[0222] There can be two movable baffles 20, with the two movable baffles 20 respectively located on the first side plate 11 and the third side plate 13. The above description of the movable baffle 20 is based on the movable baffle 20 located on the first side plate 11. The structure of the movable baffle 20 located on the third side plate 13 and its cooperation with the pool cleaning robot 200 can be found in the relevant description of the movable baffle 20 located on the first side plate 11.

[0223] Specifically, please refer to Figure 5. The towing body 10 includes a first side plate 11, a second side plate 12, a third side plate 13, and a bottom plate 14. The first side plate 11, the second side plate 12, and the third side plate 13 surround the periphery of the bottom plate 14.

[0224] The first side plate 11 and the third side plate 13 are disposed opposite each other in the width direction X. The second side plate 12 is connected between the first side plate 11 and the third side plate 13. The first side plate 11, the second side plate 12 and the third side plate 13 are respectively connected to the three sides of the base plate 14.

[0225] Optionally, the space formed by the first side plate 11, the second side plate 12, the third side plate 13, and the bottom plate 14 is the accommodating space 10a. The opening 10b is located between the first side plate 11 and the third side plate 13 and opposite to the second side plate 12. The bottom plate 14 forms the bottom wall of the accommodating space 10a. The first side plate 11, the second side plate 12, and the third side plate 13 respectively form the three side walls of the accommodating space 10a. The side of the towing body 10 opposite to the bottom wall can be open.

[0226] In a first optional embodiment, the movable baffle 20 is rotatably connected to the first side plate 11 and the third side plate 13.

[0227] Please refer to Figures 8, 10, 12, and 15. The movable baffle 20 is used to engage with the pool cleaning robot 200 in a transmission manner to be in a first state or a second state. Specifically, the movable baffle 20 can be in direct contact with the pool cleaning robot 200. The rotation of the wheels of the pool cleaning robot 200 drives the movable baffle 20 to rotate to the first state or the second state.

[0228] Alternatively, the movable baffle 20 can indirectly contact the pool cleaning robot 200. The rotation of the wheels of the pool cleaning robot 200 drives the movement of other structures, thereby causing the movable baffle 20 to rotate to either the first or second state. In other words, the movable baffle 20 can rotate from the first state to the second state, and it can also rotate from the second state to the first state.

[0229] In this embodiment, the water tank cleaning robot 200 and the movable baffle 20 are driven together to move the movable baffle 20 to the first state or the second state, thereby opening or closing the opening 10b. There is no need to set up electric drive components and transmission components, which reduces the setting of parts and devices and saves energy.

[0230] This application provides a water-removing base station 1000, which includes a base station body 300 and a towing mechanism 100. The towing mechanism 100 is movably connected to the base station body 300. The towing mechanism 100 includes a towing body 10 and a movable baffle 20. The towing body 10 has a receiving space 10a and an opening 10b communicating with the receiving space 10a. The receiving space 10a is used to receive a water tank cleaning robot 200. The movable baffle 20 is movably connected to the towing body 10 and is disposed at the opening 10b of the receiving space 10a. The movable baffle 20 is used for transmission cooperation with the water tank cleaning robot 200 to be in a first state or a second state. When the movable baffle 20 is in the first state, the movable baffle 20 closes the opening 10b. When the movable baffle 20 is in the second state, the movable baffle 20 opens the opening 10b. When the pool cleaning robot 200 climbs up the pool wall M1 from the water and moves to the location of the towing mechanism 100, the movable baffle 20 is in the open opening 10b state to allow the pool cleaning robot 200 to enter its accommodating space 10a. After the pool cleaning robot 200 has fully entered, the movable baffle 20 closes the opening 10b to achieve automatic retrieval and towing of the pool cleaning robot 200 ashore. When the pool cleaning robot 200 needs to perform a cleaning task, the towing mechanism 100 moves relative to the base station body 300 to drive the pool cleaning robot 200 towards the water surface until the towing mechanism 100 is in contact with the pool wall M1. Then the movable baffle 20 opens the opening 10b to allow the pool cleaning robot 200 to fall into the water, thereby achieving automatic water entry of the pool cleaning robot 200. The above process eliminates the need to manually submerge and remove the pool cleaning robot 200 from the water. Furthermore, the robot can be removed promptly after completing its cleaning task, reducing the risk of a shortened lifespan due to prolonged immersion in water and making the use of the pool cleaning robot 200 more convenient.

[0231] Optionally, please refer to Figures 15 and 16. The movable baffle 20 includes a first rotating arm 21, a baffle body 22, and a second rotating arm 23 connected in sequence.

[0232] The first rotating arm 21 and the second rotating arm 23 are rotatably connected to the first side plate 11 and the third side plate 13, respectively. The two ends of the baffle body 22 are bent and connected to the first rotating arm 21 and the second rotating arm 23, respectively. The baffle body 22 is arranged along the width direction X.

[0233] Referring to Figure 7, when the movable baffle 20 is in the first state, the baffle body 22 blocks the opening 10b. Optionally, the first rotating arm 21 is parallel to the base plate 14, or the extension direction of the first rotating arm 21 has a relatively large acute angle (close to 90°) with the normal direction of the base plate 14, or the extension direction of the first rotating arm 21 has a relatively small obtuse angle (close to 90°) with the normal direction of the base plate 14.

[0234] Referring to Figure 11, when the movable baffle 20 is in the second state, the baffle body 22 is located on the side where the base plate 14 of the towing body 10 is located. Optionally, the first rotating arm 21 is perpendicular or nearly perpendicular to the base plate 14. The baffle body 22 may be flush with the base plate 14, or the inner surface of the baffle body 22 may be lower than the surface of the base plate 14 (the bottom wall of the accommodating space 10a).

[0235] Optionally, referring to Figures 15 and 16, the movable baffle 20 has an inner surface 201 and an outer surface 202 disposed opposite to each other. When the movable baffle 20 is in the first state, the inner surface 201 faces the receiving space 10a. When the movable baffle 20 is in the first state, the outer surface 202 faces away from the receiving space 10a.

[0236] When the movable baffle 20 is in the first state, the baffle body 22 is opposite to the second side plate 12, and the baffle body 22 blocks the opening 10b, thus closing the opening 10b of the accommodating space 10a. The movable baffle 20, the first side plate 11, the second side plate 12, and the third side plate 13 confine the pool cleaning robot 200 within the accommodating space 10a.

[0237] When the movable baffle 20 is in the second state, the baffle body 22 is located on the side where the base plate 14 is located, and the opening 10b of the accommodating space 10a is opened, so that the pool cleaning robot 200 can exit the accommodating space 10a from the opening 10b or enter the accommodating space 10a from the outside through the opening 10b.

[0238] Optionally, referring to Figures 23 and 25, the first side plate 11 has a first rotating groove 11a near the opening 10b, and the first rotating arm 21 is rotatably connected to the bottom wall of the first rotating groove 11a. The first rotating groove 11a has a first groove sidewall 111 and a second groove sidewall 112 that intersect each other.

[0239] When the first rotating arm 21 rotates to abut against the side wall 111 of the first groove, the movable baffle 20 is in a first state. When the first rotating arm 21 rotates to abut against the side wall 112 of the second groove, the movable baffle 20 is in a second state.

[0240] Optionally, the first groove sidewall 111 faces the side where the base plate 14 is located. Furthermore, the plane containing the first groove sidewall 111 is parallel or nearly parallel to the plane containing the base plate 14.

[0241] Optionally, the second groove sidewall 112 faces away from the side where the second side plate 12 is located. Furthermore, the plane containing the second groove sidewall 112 is perpendicular or nearly perpendicular to the plane containing the bottom plate 14.

[0242] The first groove sidewall 111 is located on the side of the second groove sidewall 112 that is away from the second side plate 12. The second groove sidewall 112 is in contact with the end face of the bottom plate 14 that is away from the second side plate 12. Thus, when the movable baffle 20 is in the second state, the baffle body 22 is close to or in contact with the bottom plate 14, so that the opening 10b is fully opened.

[0243] Correspondingly, the third side plate 13 has a second rotating groove near the opening 10b, and the second rotating arm 23 is rotatably connected to the bottom wall of the second rotating groove. The second rotating groove has a third groove side wall and a fourth groove side wall that intersect each other.

[0244] Optionally, the third groove sidewall faces the side where the base plate 14 is located. Furthermore, the plane containing the third groove sidewall is parallel or nearly parallel to the plane containing the base plate 14.

[0245] Optionally, the fourth groove sidewall faces away from the side where the second side plate 12 is located. Furthermore, the plane containing the fourth groove sidewall is perpendicular or nearly perpendicular to the plane containing the bottom plate 14.

[0246] The third groove sidewall is located on the side of the fourth groove sidewall that is away from the second side plate 12. The fourth groove sidewall is in contact with the end face of the bottom plate 14 that is away from the second side plate 12.

[0247] When the first rotating arm 21 rotates to abut against the first groove sidewall 111, and the second rotating arm 23 rotates to abut against the third groove sidewall, the movable baffle 20 is in a first state. When the first rotating arm 21 rotates to abut against the second groove sidewall 112, and the second rotating arm 23 rotates to abut against the fourth groove sidewall, the movable baffle 20 is in a second state.

[0248] In one optional embodiment, after the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 is no longer subjected to the force of the track 210, and the movable baffle 20 can be restored to the first state by the action of the reset structure (described in detail in the following embodiments). In another optional embodiment, after the pool cleaning robot 200 has fully entered the accommodating space 10a, the tail end of the track 210 of the pool cleaning robot 200 can drive the movable baffle 20 to rotate to the first state.

[0249] Further optionally, referring to Figures 4, 8, 10, 12, and 15, the outer surface of the track 210 is provided with a plurality of fourth protrusions 26. The fourth protrusions 26 include, but are not limited to, raised dots or raised strips. In this embodiment, the fourth protrusions 26 are raised strips. The fourth protrusions 26 extend along the width direction X.

[0250] Please refer to Figures 8, 10, 12, and 15. The movable baffle 20 has a plurality of second protrusions 24 on its surface facing the accommodating space 10a. The second protrusions 24 include, but are not limited to, raised dots or raised strips. In this embodiment, the second protrusions 24 are raised strips. The second protrusions 24 extend along the width direction X.

[0251] When the track 210 contacts the movable baffle 20 and the track 210 rolls outward toward the accommodating space 10a, at least a portion of the fourth protrusion 26 engages with at least a portion of the second protrusion 24. The movable baffle 20 moves from the first state to the second state under the action of the track 210.

[0252] Specifically, please refer to Figures 8, 10, 12 and 15 in sequence. When the tail end of the track 210 contacts the inner surface 201 of the movable baffle 20 and the track 210 rolls outward toward the accommodating space 10a, at least a portion of the fourth protrusion 26 engages with at least a portion of the second protrusion 24 to increase the friction between the track 210 and the movable baffle 20, which makes it easier for the track 210 to drive the movable baffle 20 to rotate and open the opening 10b.

[0253] Optionally, referring to Figures 5 and 16, the outer surface of the track 210 is provided with a plurality of fourth protrusions 26. The surface of the movable baffle 20 facing away from the accommodating space 10a is provided with a plurality of third protrusions 25. The third protrusions 25 include, but are not limited to, raised dots or raised strips. In this embodiment, the third protrusion 25 is a raised strip. The third protrusion 25 extends along the width direction X.

[0254] Referring to Figure 16, when the track 210 contacts the movable baffle 20 and the track 210 rolls toward the accommodating space 10a, at least a portion of the fourth protrusion 26 engages with at least a portion of the third protrusion 25. The movable baffle 20 moves from the first state to the second state under the action of the track 210.

[0255] Specifically, please refer to Figure 16. When the front end of the track 210 contacts the outer surface 202 of the movable baffle 20 and the track 210 rolls toward the accommodating space 10a, at least a portion of the third protrusion 25 engages with at least a portion of the fourth protrusion 26 to increase the friction between the track 210 and the movable baffle 20, which makes it easier for the track 210 to drive the movable baffle 20 to rotate and open the opening 10b.

[0256] Optionally, the inner surface 201 of the movable baffle 20 may be provided with a second protrusion 24, and the outer surface 202 of the movable baffle 20 may be provided with a third protrusion 25. Thus, before the pool cleaning robot 200 enters the accommodating space 10a and before it exits the accommodating space 10a, the movable baffle 20 can be rotated to a second state by the rotation of the track 210 of the pool cleaning robot 200. The second protrusion 24 on the inner surface 201 and the third protrusion 25 on the outer surface 202 of the movable baffle 20 can both cooperate with the fourth protrusion 26 on the track 210 to increase transmission friction and improve the transmission efficiency of the pool cleaning robot 200 in driving the movable baffle 20 to open or close the opening 10b by rotating its own track 210.

[0257] Optionally, the rotation direction of the track 210 when the pool cleaning robot 200 exits from the accommodating space 10a is opposite to the rotation direction of the track 210 when the pool cleaning robot 200 enters the accommodating space 10a.

[0258] Optionally, please refer to Figures 26 and 27. When the pool cleaning robot 200 is in the accommodating space 10a, for example, when the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12 (described in detail later), the movable baffle 20 is spaced apart from the pool cleaning robot 200 during the rotation from the second state to the first state. This is to avoid the movable baffle 20 interfering with the pool cleaning robot 200 during the rotation, which would prevent the movable baffle 20 from rotating to the first or second state.

[0259] Optionally, the movement trajectory of the movable baffle 20 from the first state to the second state is an arc-shaped trajectory. The rotation trajectory of the movable baffle 20 is approximately a quarter-circle arc.

[0260] Further optional, referring to Figures 26 and 27, the rotation arc of the movable baffle 20 is approximately a quarter-circle arc. The movable baffle 20 rotates from the first state to the second state around the quarter-circle arc track 210 of the pool cleaning robot 200. When the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12, the movable baffle 20 is spaced apart from the quarter-circle arc track 210 of the pool cleaning robot 200 during its rotation from the second state to the first state. Further optional, the gap formed between the movable baffle 20 and the quarter-circle arc track 210 of the pool cleaning robot 200 during its rotation from the second state to the first state can be a uniform gap or a non-uniform gap.

[0261] As a further optional step, please refer to Figures 26 and 27. When the pool cleaning robot 200 is in the accommodating space 10a, the rotation axis of the movable baffle 20 is concentrically arranged with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200.

[0262] Specifically, the rotation axis of the movable baffle 20 is the center line of the rotation axis of the first rotating arm 21. Viewed from a cross-section along the height direction Z and the length direction Y, the rotation axis of the movable baffle 20 is the center position of the rotation axis of the first rotating arm 21 (the center position of a circular rotation axis).

[0263] Viewed from the cross section along the height direction Z and the length direction Y, the axis of the pool cleaning robot 200 250 (e.g., the aforementioned rear track wheel 230) is located at the center of the circle of the pool cleaning robot 200 250 (e.g., the aforementioned rear track wheel 230).

[0264] In this embodiment, when the pool cleaning robot 200 is within the accommodating space 10a (for example, the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12), by concentrically arranging the rotation axis of the movable baffle 20 with the axis of the walking wheel 250 (for example, the aforementioned rear track wheel 230) of the pool cleaning robot 200, the inner surface of the movable baffle 20 has a gap with the outer surface of the walking wheel 250 in the first state when the pool cleaning robot 200 is within the accommodating space 10a. Furthermore, it can have a minimum gap, so that the space is small when the pool cleaning robot 200 retreats to abut the inner surface of the movable baffle 20. This avoids a large gap between the pool cleaning robot 200 and the front end limiting member 51 when the pool cleaning robot 200 retreats to abut the inner surface of the movable baffle 20, which would prevent the front end limiting member 51 from being unable to limit the front end of the pool cleaning robot 200, causing the pool cleaning robot 200 to fall out of the accommodating space 10a and overturn.

[0265] Furthermore, the rotation axis of the movable baffle 20 is concentrically arranged with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. Thus, when the pool cleaning robot 200 is in the accommodating space 10a, the inner surface of the movable baffle 20 has a gap with the outer surface of the walking wheel 250 in the second state, and can further have a minimum gap. Thus, the height of the step surface formed by the inner surface of the movable baffle 20 and the surface of the base plate 14 is small, which is more conducive to the pool cleaning robot 200 entering the accommodating space. In addition, it is also conducive to the movable baffle 20 not being subjected to the downward pressure of the walking wheel 250 in the second state, and thus facilitates its return to the first state under the action of the reset structure.

[0266] Furthermore, the rotation axis of the movable baffle 20 is concentrically arranged with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. In this way, the movable baffle 20 rotates around the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230), that is, around the portion of the track 210 corresponding to the rear track wheel 230 (e.g., the 1 / 4 arc track 210), to ensure that the gap between the inner surface 201 of the movable baffle 20 and the 1 / 4 arc track 210 is relatively uniform. Furthermore, the movable baffle 20 has a minimum gap during the rotation of the walking wheel 250 (e.g., the aforementioned rear track wheel 230).

[0267] Furthermore, referring to Figure 27, the rotation radius R2 of the inner surface 201 of the movable baffle 20 can be slightly larger than the radius R1 corresponding to the 1 / 4 arc track 210, so as to ensure that the movable baffle 20 will not interfere with the surface of the track 210 during rotation, and the gap is consistent and small.

[0268] Optionally, the difference between the rotation radius of the inner surface 201 of the movable baffle 20 and the radius R1 corresponding to the 1 / 4 arc track 210 is the minimum gap, to ensure that the movable baffle 20 does not interfere with the surface of the track 210 during rotation, and the gap is consistent and minimal. On the one hand, the size of the first rotating arm 21 of the movable baffle 20 is relatively small, thereby making the height and length dimensions of the towing mechanism 100 relatively small. On the other hand, when the pool cleaning robot 200 is in the accommodating space 10a, the tail end of the pool cleaning robot 200 and the movable baffle 20 are within the accommodating space 10a. The large gap allows the pool cleaning robot 200 to slide down a large area within the accommodating space 10a, making it easy for the front end of the pool cleaning robot 200 to separate from the front limiting member 51 (described in detail later), thus causing the pool cleaning robot 200 to detach and tip over within the accommodating space 10a. In this embodiment, by setting the gap between the tail end of the pool cleaning robot 200 and the movable baffle 20 to be smaller, even though the pool cleaning robot 200 has less room to slide down within the accommodating space 10a, the problem of the pool cleaning robot 200 detaching and tipping over within the accommodating space 10a is less likely to occur.

[0269] Further, please refer to Figure 27. The outer surface of the track 210 is provided with a fourth protrusion 26, and the inner surface 201 of the movable baffle 20 is provided with a second protrusion 24. The difference between the rotation radius of the movable baffle 20 and the radius R1 corresponding to the 1 / 4 arc track 210 is the minimum clearance, which means that the distance between the end of the fourth protrusion 26 and the end of the second protrusion 24 is the minimum clearance.

[0270] Of course, in other embodiments, when the pool cleaning robot 200 is within the accommodating space 10a, the rotation axis of the movable baffle 20 is not concentric with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. For example, the rotation axis of the movable baffle 20 and the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) are collinear in the length direction Y. Optionally, when the movable baffle 20 is in the first state, the line connecting the center of the baffle body 22 and the rotation axis of the walking wheel 250 is parallel to the bottom plate 14. In this way, when the towing mechanism 100 is in contact with the pool wall M1, the pool cleaning robot 200 is in a vertical state and the tail end of the track 210 of the pool cleaning robot 200 abuts against the baffle body 22, which can reduce the eccentricity and thus reduce problems such as instability and detachment of the pool cleaning robot 200.

[0271] For example, the rotation axis of the movable baffle 20 is collinear with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200 in the height direction Z. Of course, the proximity of the rotation axis of the movable baffle 20 to the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200 ensures that the distance between the movable baffle 20 and the 1 / 4 arc track 210 is similar during rotation, reducing the risk of detachment and tipping over in the accommodating space 10a, and also reducing the size of the towing body 10.

[0272] Optionally, referring to Figure 27, the rotation radius R2 of the inner surface 201 of the movable baffle 20 is greater than the radius R1 of the outer contour circle of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. Referring to Figure 26, the rotation radius R3 of the outer surface 202 of the movable baffle 20 is less than the distance between the rotation axis of the movable baffle 20 and the back surface of the towing body 10, the back surface of the towing body 10 being opposite to the bottom wall of the accommodating space 10a. The back surface of the towing body 10 is the surface of the bottom plate 14 facing away from the accommodating space 10a. The rotation radius R3 of the outer surface 202 of the movable baffle 20 is less than the distance H1 between the rotation axis of the movable baffle 20 and the pool wall M1 when the towing body 10 is in the first position W1.

[0273] Specifically, the pool cleaning robot 200 is located within the accommodating space 10a. For example, the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12. At this time, the rotation radius R2 of the inner surface 201 of the movable baffle 20 is greater than the radius R1 of the outer contour circle of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. The outer contour circle of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200 refers to a circle with the center of the projection of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) along the width direction X as its center, and the distance between the farthest point on the corresponding 1 / 4 arc track 210 during the rotation of the movable baffle 20 and the center of the circle as its radius.

[0274] When the outer surface of the track 210 is provided with a fourth protrusion 26, the radius R1 of the outer contour circle of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200 is the distance between the end point of the fourth protrusion 26 on the corresponding 1 / 4 arc track 210 and the center of the projection circle of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) during the rotation of the movable baffle 20.

[0275] Specifically, the pool cleaning robot 200 is located within the accommodating space 10a. For example, the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12. At this time, the rotation radius R3 of the outer surface 202 of the movable baffle 20 is less than the distance H1 between the rotation axis of the movable baffle 20 and the pool wall M1 when the towing body 10 is in the first position W1, thereby avoiding the collision between the movable baffle 20 and the pool wall M1 when the movable baffle 20 rotates to the second state.

[0276] From another perspective, referring to Figures 28 and 29, when the movable baffle 20 is in the second state, the maximum distance between the inner surface 201 and the outer surface of the movable baffle 20 (the distance between the endpoints of the second protrusion 24 and the third protrusion 25 in the height direction Z) is less than the minimum distance between the outer surface of the track 210 (the endpoint of the fourth protrusion 26) and the pool wall M1. Thus, the movable baffle 20 can enter the gap between the outer surface of the track 210 and the pool wall M1 in the second state, and avoids motion interference between the movable baffle 20 and the pool wall M1 and the outer surface of the track 210 when the movable baffle 20 rotates to the second state. In Figure 28, the rotation axis of the movable baffle 20 is concentrically arranged with the axis of the walking wheel 250 of the pool cleaning robot 200 (e.g., the aforementioned rear track wheel 230). In Figure 29, the rotation axis of the movable baffle 20 is collinear with the axis of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200 along the length direction.

[0277] Optionally, referring to Figure 30, when the movable baffle 20 is in the second state, the inner surface 201 of the movable baffle 20 has a gap H2 with the bottom surface of the walking wheel 250 (e.g., the aforementioned rear track wheel 230) of the pool cleaning robot 200. Specifically, the inner surface 201 of the movable baffle 20 is lower than the surface of the base plate 14 (the bottom wall of the accommodating space 10a).

[0278] On the one hand, it avoids motion interference between the movable baffle 20 and the outer surface (bottom surface) of the track 210 when the movable baffle 20 rotates to the second state; on the other hand, it ensures that the pool cleaning robot 200 is within the accommodating space 10a (after entering the position). For example, the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12, and the track 210 on the outer side of the rear track wheel 230 will not contact the movable baffle 20, so that the movable baffle 20 can be smoothly reset (to the first state) under the action of the reset structure.

[0279] Optionally, when the movable baffle 20 is rotated to the second state, the first rotating arm 21 is perpendicular to the base plate 14 and abuts against the second groove sidewall 112, and the movable baffle 20 abuts against the end face of the base plate 14 away from the second side plate 12. The pool cleaning robot 200 is located within the accommodating space 10a (after entering its position). For example, when the front end of the pool cleaning robot 200 abuts against the front end limiting member 51 on the second side plate 12, the rotation axis of the movable baffle 20 is located at the same position as the rotation axis of 250 (e.g., the aforementioned rear track wheel 230). The orthographic projection of the rotation axis of the movable baffle 20 in the height direction Z is located on the baffle body 22, i.e., outside the base plate 14. In other words, when the movable baffle 20 is rotated to the second state, it is located below the straight portion of the track 210. If there is a gap between the inner surface 201 of the movable baffle 20 and the bottom surface of the 250 of the pool cleaning robot 200 (e.g., the aforementioned rear track wheel 230), the movable baffle 20 will not be pressed by the straight part of the track 210, thus preventing it from returning to the first state under the action of the reset structure.

[0280] If the inner surface 201 of the movable baffle 20 is flush with the surface of the bottom plate 14 (bottom wall of the accommodating space 10a) of the pool cleaning robot 200, the movable baffle 20 will be pressed against the straight part of the track 210 when it is located below the straight part of the track 210 when it rotates to the second state, causing the movable baffle 20 to be unable to return to the first state under the action of the reset structure. If the movable baffle 20 is to be successfully reset from the second state under the action of the reset structure, the position of the movable baffle 20 in the second state needs to be moved back to below the arc surface corresponding to the track 210. Thus, even if the movable baffle 20 is reset to the first state, the distance between the baffle body 22 and the track 210 will be large. On the one hand, this increases the length of the entire towing body 10, and on the other hand, it increases the space in which the pool cleaning robot 200 can slide down in the accommodating space 10a. This makes it easy for the front end of the pool cleaning robot 200 to separate from the front limiting member 51 (described in detail later), and thus the pool cleaning robot 200 may fall off and overturn in the accommodating space 10a. However, in this embodiment, by setting the gap between the tail end of the pool cleaning robot 200 and the movable baffle 20 to be small, even if the space in which the pool cleaning robot 200 can slide down in the accommodating space 10a is small, it is less likely to cause problems such as the pool cleaning robot 200 falling off and overturning in the accommodating space 10a.

[0281] Optionally, referring to Figure 26, the inner surface of the baffle body 22 includes an inclined guide surface 221. The inclined guide surface 221 is used to form a guide slope for guiding the pool cleaning robot 200 into the accommodating space 10a when the movable baffle 20 is in the second state. In other words, the inclined guide surface 221 is used to form a guide slope between the bottom plate 14 and the pool wall M1 when the movable baffle 20 is in the second state. The height of the guide slope gradually decreases in the direction away from the bottom plate 14, so that the tracks 210 of the pool cleaning robot 200 remain in contact with the surface below during the process of the pool cleaning robot 200 entering the accommodating space 10a from the pool wall M1, thereby improving the smoothness of the pool cleaning robot 200's movement into the accommodating space 10a.

[0282] Alternatively, referring to Figure 16, the outer contour of the baffle body 22 is arc-shaped. Optionally, the outer surface of the baffle body 22 is arc-shaped. For example, when the pool cleaning robot 200 contacts the outer surface of the baffle body 22 in its first state outside the accommodating space 10a, the track 210 of the pool cleaning robot 200 first contacts the bottom end (third protrusion 25) of the outer surface of the baffle body 22. As the pool cleaning robot 200 moves forward, it presses down on the baffle body 22 (rotates it downwards at a certain angle), and the outer surface of the baffle body 22 also becomes arc-shaped, allowing the pool cleaning robot 200 to gradually contact the top end (third protrusion 25) of the outer surface of the baffle body 22 after the baffle body 22 has rotated downwards at a certain angle.

[0283] Optionally, referring to Figures 8, 10, 12, and 15, the towing mechanism 100 includes a limiting member 51 (i.e., the aforementioned front limiting member 51). The limiting member 51 is disposed on the towing body 10 and is disposed opposite to the opening 10b. Specifically, the limiting member 51 is disposed on the second side plate 12. When the pool cleaning robot 200 moves into the accommodating space 10a, the limiting member 51 cooperates with the movable baffle 20 to limit the pool cleaning robot 200. Further, the limiting member 51 cooperates with the movable baffle 20 to limit the pool cleaning robot 200 in the traveling direction (forward and backward direction) and the height direction Z, so that the pool cleaning robot 200 can be stably restrained within the accommodating space 10a.

[0284] Specifically, the orthographic projection of the limiting member 51 onto the surface of the base plate 14 is at least partially located on the base plate 14, thus at least a portion of the limiting member 51 protrudes from the second side plate 12. Further, a recessed space is formed between the limiting member 51, the second side plate 12, and the base plate 14 to accommodate the front end of the pool cleaning robot 200. At least a portion of the limiting member 51 is located on the top side of the front end of the pool cleaning robot 200, and the limiting member 51 cooperates with the base plate 14 to limit the pool cleaning robot 200 in the height direction Z. The height direction Z is perpendicular to the base plate 14.

[0285] Further, referring to Figure 8, when the front end of the pool cleaning robot 200 abuts against the limiting member 51 and the movable baffle 20 is in the first state, the movable baffle 20, in cooperation with the limiting member 51, can also limit the front-back direction of the pool cleaning robot 200. In this application, the front-back direction can also refer to the length direction Y, that is, the direction perpendicular to the second side plate 12.

[0286] Optionally, the limiting member 51 can roll relative to the towing body 10 to reduce friction between the limiting member 51 and the track 210 (or the wheel 250) when the limiting member 51 is in contact with the track 210 (or the wheel 250) and the track 210 (or the wheel 250) is rotating.

[0287] Optionally, referring to Figures 7, 8, 10, 12, and 15, the limiting member 51 is a roller. The distance between the rolling axis of the limiting member 51 and the bottom wall (bottom plate 14) of the accommodating space 10a is greater than the distance between the rotation axis of the walking wheel 250 and the bottom wall (bottom plate 14) of the accommodating space 10a when the pool cleaning robot 200 is located in the accommodating space 10a. Thus, the limiting member 51 abuts against the top of the front end of the walking wheel 250, thereby limiting the pool cleaning robot 200 in the height direction Z with the bottom plate 14; the limiting member 51 and the movable baffle 20 in the first state limit the pool cleaning robot 200 in the length direction Y.

[0288] In addition, the limiting component 51 can not only limit the water tank cleaning robot 200, but also play a transmission role.

[0289] Specifically, referring to Figures 18 and 19, the limiting member 51 is capable of rolling relative to the towing body 10. The towing body 10 also includes a linkage member 52. The linkage member 52 is connected between the limiting member 51 and the movable baffle 20. When the pool cleaning robot 200 moves into the accommodating space 10a, the limiting member 51 contacts the walking wheels 250 (or tracks 210) of the pool cleaning robot 200.

[0290] When the traveling wheel 250 (or track 210) rotates, the traveling wheel 250 (or track 210) drives the linkage 52 to rotate through the limiting member 51. The limiting member 51 and the linkage 52 cooperate to drive the movable baffle 20 to move to the first state.

[0291] Optionally, the linkage 52 includes, but is not limited to, a friction belt or a transmission belt. One end of the friction belt is connected to the limiting member 51, and the other end of the friction belt is connected to the first rotating arm 21. When the track 210 rotates, the track 210 drives the linkage 52 to rotate through the limiting member 51, thereby driving the movable baffle 20 to rotate to the first state or the second state, so as to open the movable baffle 20 when the pool cleaning robot 200 prepares to open the accommodating space 10a and close the movable baffle 20 after the pool cleaning robot 200 enters the accommodating space 10a.

[0292] Please refer to Figures 18 and 19. The linkage 52 includes a first rotating member 41, a friction belt 42, and a second rotating member 43. The friction belt 42 connects the first rotating member 41 and the second rotating member 43. The second rotating member 43 is connected to the limiting member 51.

[0293] Please refer to Figures 18 and 19. The first rotating member 41 is connected to one end of the movable baffle 20. Optionally, the first rotating member 41 includes a first rotating gear 411, a second rotating gear 412, and a first rotating wheel 413. The first rotating gear 411 is coaxially connected to the first rotating arm 21. The second rotating gear 412 is coaxially connected to the first rotating wheel 413. Further, the second rotating gear 412 and the first rotating wheel 413 may be integrally formed in the axial direction. The first rotating gear 411 and the second rotating gear 412 mesh. The second rotating member 43 includes, but is not limited to, a second transmission wheel, which is coaxially connected to the limiting member 51.

[0294] The limiting member 51 is disposed in the accommodating space 10a and located on the side opposite to the opening 10b. Further, the limiting member 51 is rotatably mounted on the second side plate 12. Optionally, the limiting member 51 is a roller.

[0295] When the limiting member 51 rolls under the action of the pool cleaning robot 200, it drives the movable baffle 20 to be in the first state or the second state.

[0296] Specifically, when the pool cleaning robot 200 is located in the accommodating space 10a, the front end of the walking wheel 250 contacts the limiting member 51. The walking wheel 250 rotates, causing the limiting member 51 to rotate. The rotation of the limiting member 51 causes the second rotating wheel (second rotating member 43), friction belt 42, first rotating wheel 413, and second rotating gear 412 to rotate synchronously, thereby causing the first rotating gear 411 and the first rotating arm 21 of the movable baffle 20 to rotate.

[0297] When the track 210 rotates in the first rotation direction, it drives the movable baffle 20 to move to the first state, thereby controlling the closing of the opening 10b. When the traveling wheel 250 rotates in the opposite direction of the first rotation direction, it drives the movable baffle 20 to move to the second state, thereby controlling the opening 10b to open.

[0298] In this embodiment, there is no need to set up a motor structure. By controlling the rotation direction of the track 210, the movable baffle 20 can be controlled to move to the first state or the second state, and then the opening 10b can be automatically controlled to close or open through transmission.

[0299] Optionally, the number of linkage components 52 and limiting components 51 can be one or two sets. When there are two sets of linkage components 52 and limiting components 51, the two sets of linkage components 52 and limiting components 51 are respectively installed on the first side plate 11 and the third side plate 13. The two sets of limiting components 51 are spaced apart along the width direction X. The two limiting components 51 respectively cooperate with the two sets of tracks 210 for transmission.

[0300] In this embodiment, by setting two sets of linkage components 52 and limiting components 51, a force is applied evenly to both sides of the movable baffle 20, so that the movable baffle 20 rotates smoothly and avoids problems such as jamming during rotation.

[0301] Alternatively, the two sets of limiting members 51 can be combined into one roller.

[0302] Optionally, referring to Figures 23-25, the base plate 14 is provided with a plurality of protrusions 141. The protrusions 141 are arranged in a direction (width direction X) opposite to the first side plate 11 and the second side plate 12. The protrusions 141 are used to cooperate with the tracks 210 of the pool cleaning robot 200 when the pool cleaning robot 200 is in the accommodating space 10a.

[0303] Specifically, the base plate 14 may be provided with two sets of protrusions 141, which are spaced apart in the width direction X. Each set of protrusions 141 includes a plurality of protrusions 141. The plurality of protrusions 141 are arranged sequentially along the length direction Y. The protrusions 141 are convex strips extending in the width direction X.

[0304] Each set of protrusions 141 engages with a track 210 to increase the friction between the pool cleaning robot 200 and the base plate 14.

[0305] Optionally, as shown in Figures 23-25, the base plate 14 is provided with a brush groove 142 near the second side plate 12. The brush groove 142 is used to accommodate the cleaning brush of the pool cleaning robot 200 when the pool cleaning robot 200 is in the accommodating space 10a, so as to prevent the cleaning brush of the pool cleaning robot 200 from being deformed by the pressure of the base plate 14.

[0306] Optionally, as shown in Figures 6, 7, 9 and 11, the towing body 10 also includes a first guide plate 15 and a second guide plate 16.

[0307] The first guide plate 15 is disposed on the side of the first side plate 11 away from the second side plate 12. The second guide plate 16 is disposed on the side of the third side plate 13 away from the second side plate 12. The first guide plate 15 extends from the first side plate 11 in a direction gradually away from the third side plate 13. The second guide plate 16 extends from the third side plate 13 in a direction gradually away from the first side plate 11. The distance between the first guide plate 15 and the second guide plate 16 gradually increases in the direction along the length direction Y and away from the second side plate 12. In other words, a relatively wide opening is formed between the first guide plate 15 and the second guide plate 16 so that the pool cleaning robot 200 can move to the opening 10b under the guidance of the first guide plate 15 and the second guide plate 16 before entering the receiving space 10a, even if it is not directly facing the opening 10b.

[0308] Optionally, the first side plate 11 includes a first limiting portion (the aforementioned first groove sidewall 111). The first limiting portion cooperates with the first rotating arm 21 to limit the movable baffle 20 when it is in the first state. The first limiting portion may be the aforementioned first groove sidewall 111. The structure and function of the first limiting portion can refer to the structure and function of the first groove sidewall 111.

[0309] The first side plate 11 includes a second limiting part (the aforementioned second groove sidewall 112). The second limiting part cooperates with the first rotating arm 21. It limits the movable baffle 20 when it is in the second state. The second limiting part can be the aforementioned second groove sidewall 112. The structure and function of the second limiting part can refer to the structure and function of the second groove sidewall 112.

[0310] Further optionally, referring to Figure 31, the first side plate 11 includes a first side plate body (not shown) and a first shielding plate 113. The first side plate body has the aforementioned first rotating groove 11a. The first rotating arm 21 rotates within the first rotating groove 11a. The first shielding plate 113 is opposite to the bottom wall of the first rotating groove 11a and covers the first rotating groove 11a and the first rotating arm 21, thereby preventing the pool cleaning robot 200 from deviating to the left and getting stuck in the first rotating groove 11a during its entry into the receiving space 10a. In this embodiment, even if the pool cleaning robot 200 deviates to the left during its entry into the receiving space 10a, the first shielding plate 113 prevents the pool cleaning robot 200 from getting stuck in the first rotating groove 11a and allows the pool cleaning robot 200 to gradually return to its correct position during its forward movement.

[0311] The third side plate 13 includes a second side plate body (not shown) and a second baffle plate (not shown). The second side plate body has the aforementioned second rotating groove. The second rotating arm 23 rotates within the second rotating groove. The second baffle plate is opposite to the bottom wall of the first rotating groove 11a and covers the second rotating groove and the second rotating arm 23, thereby preventing the pool cleaning robot 200 from deviating to the right and getting stuck in the second rotating groove during its entry into the receiving space 10a. In this embodiment, even if the pool cleaning robot 200 deviates to the right during its entry into the receiving space 10a, the second baffle plate prevents the pool cleaning robot 200 from getting stuck in the second rotating groove and allows the pool cleaning robot 200 to gradually return to its correct position during its forward movement.

[0312] Optionally, referring to Figure 17, the towing mechanism 100 further includes a reset structure 40 connected between the movable baffle 20 and the towing body 10. The reset structure 40 is used to drive the movable baffle 20, which is in the second state, back to the first state.

[0313] Specifically, when the pool cleaning robot 200 enters the accommodating space 10a, the movable baffle 20 is in the second state, and the opening 10b is open. After the pool cleaning robot 200 has fully entered the accommodating space 10a, the reset structure 40 drives the movable baffle 20, which is in the second state, to return to the first state, thereby closing the opening 10b and restraining (limiting) the pool cleaning robot 200 within the accommodating space 10a, preventing the pool cleaning robot 200 from falling out of the accommodating space 10a. This allows the towing mechanism 100 to move relative to the base station body 300 to move the pool cleaning robot 200 away from the water surface until the towing mechanism 100 is stacked on the base station body 300, thereby realizing the automatic removal of the pool cleaning robot 200 from the pool.

[0314] Optionally, the number of reset structures 40 is two sets. The two sets of reset structures 40 are respectively disposed between the first rotating arm 21 and the first side plate 11, and between the second rotating arm 23 and the third side plate 13.

[0315] In addition, the aforementioned limiting member 51 and linkage member 52 can also serve as the reset structure 40.

[0316] In a second optional implementation, as shown in Figures 20 to 22, the movable baffle 20 is slidably connected to the towing body 10. The movable baffle 20 can slide to either the first state or the second state.

[0317] Specifically, please refer to Figures 20 to 22, where there are two movable baffles 20.

[0318] Please refer to Figures 20 and 22. The two movable baffles 20 are respectively disposed on two opposite side plates of the towing body 10. For example, the first movable baffle 20a is disposed on the first side plate 11, and the second movable baffle 20b is disposed on the third side plate 13.

[0319] Each of the movable baffles 20 is slidably connected to the side plate of the towing body 10.

[0320] Referring to Figure 20, when the movable baffle 20 is in the first state, at least a portion of the movable baffle 20 protrudes from the side plate. Referring to Figure 22, when the movable baffle 20 is in the second state, the movable baffle 20 slides and retracts into the side plate.

[0321] Specifically, the first side plate 11 has a first chamber (not shown). For example, a first movable baffle 20a is slidably connected to the first side plate 11. A first elastic mechanism (not shown) is provided between the first movable baffle 20a and the chamber wall of the first chamber.

[0322] Please refer to Figure 20. In the first state, under the action of the first elastic mechanism, a portion of the first movable baffle 20a protrudes from the first side plate 11, and the other portion is located in the first chamber and abuts against the chamber wall of the first chamber, so that the first movable baffle 20a remains relatively stable.

[0323] Referring to Figure 22, the first movable baffle 20a retracts into the first chamber under the compressive force from the first side plate 11 perpendicular to it. At this time, the first movable baffle 20a is in the second state, and the opening 10b is in the open state. After the compressive force is removed, the first movable baffle 20a returns to the first state under the action of the first elastic mechanism, and the opening 10b is in the closed state.

[0324] Correspondingly, the third side plate 13 has a second chamber. For example, a second movable baffle 20b is slidably connected to the third side plate 13. A second elastic mechanism is provided between the second movable baffle 20b and the chamber wall of the second chamber. In the first state, under the action of the second elastic mechanism, a portion of the second movable baffle 20b protrudes from the third side plate 13, and another portion is located inside the second chamber and abuts against the chamber wall of the second chamber, so that the second movable baffle 20b remains relatively stable.

[0325] The second movable baffle 20b retracts into the second chamber under the extrusion force from the perpendicular side plate 13. At this time, the second movable baffle 20b is in the second state, and the opening 10b is in the open state. After the extrusion force is removed, the second movable baffle 20b returns to the first state under the action of the second elastic mechanism, and the opening 10b is in the closed state.

[0326] Further optionally, referring to Figures 20 and 22, the movable baffle 20 (first movable baffle 20a and / or second movable baffle 20b) includes a blocking surface 204 facing the accommodating space 10a and a sliding guide surface 205 facing away from the accommodating space 10a. Taking the first movable baffle 20a as an example, in the first state, the blocking surface 204 is perpendicular or nearly perpendicular to the first side plate 11.

[0327] The sliding guide surface 205 is inclined relative to the blocking surface 204. Optionally, the sliding guide surface 205 can be a plane or an arc surface. Furthermore, the end of the sliding guide surface 205 near the blocking surface 204 is relatively far from the first side plate 11, while the end of the sliding guide surface 205 far from the blocking surface 204 is close to the first side plate 11. In other words, the movable baffle 20 has a wedge-shaped structure, a triangular block structure, etc.

[0328] When the pool cleaning robot 200 abuts against the sliding guide surface 205 and moves toward the accommodating space 10a, since the sliding guide surface 205 is an inclined surface, the pool cleaning robot 200 abuts against the sliding guide surface 205 and forms a force perpendicular to the first side plate 11, which compresses the first elastic mechanism. The movable baffle 20 moves to the second state under the compression of the pool cleaning robot 200, and the opening 10b is in the open state so that the pool cleaning robot 200 can enter the accommodating space 10a.

[0329] After the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 is restored to the first state under the action of the reset structure 40 (first elastic mechanism or second elastic mechanism), and the opening 10b is in the closed state.

[0330] When the opening 10b is closed, and the pool cleaning robot 200 abuts against the blocking surface 204, since the blocking surface 204 is nearly perpendicular to the first side plate 11, the pool cleaning robot 200 will not generate a force perpendicular to the first side plate 11 when it abuts against the sliding guide surface 205. Therefore, the movable baffle 20 is in the first state to support the tail end of the pool cleaning robot 200 and prevent the pool cleaning robot 200 from falling out of the accommodating space 10a.

[0331] The above description of the movable baffle 20 is based on the first movable baffle 20a. The structure of the second movable baffle 20b and its cooperation with the pool cleaning robot 200 can be found in the relevant description of the first movable baffle 20a.

[0332] Further optionally, referring to Figures 20 and 22, the movable baffle 20 also includes a roller 203. The roller shaft of the roller 203 is arranged along the height direction of the first side plate 11. The roller 203 can rotate freely around the roller shaft. The roller 203 is located at the end where the sliding guide surface 205 intersects with the blocking surface 204.

[0333] In this embodiment, a roller 203 is provided at the end of the movable baffle 20. During the process of the pool cleaning robot 200 entering the accommodating space 10a, the roller 203 can roll relative to the side of the pool cleaning robot 200 to reduce the forward resistance of the pool cleaning robot 200 and enable the pool cleaning robot 200 to enter the accommodating space 10a more smoothly.

[0334] In a third optional embodiment, the movable baffle 20 is oscillatingly connected to the towing body 10. The movable baffle 20 oscillates to either the first state or the second state.

[0335] Optionally, the towing mechanism 100 further includes a swing shaft (not shown) and a reset structure (not shown). The swing shaft is disposed on the side plate of the towing body 10 along a first direction. The first direction is the aforementioned height direction.

[0336] One end of the movable baffle 20 is rotatably connected to the swing shaft, and the other end of the movable baffle 20 swings around the swing shaft to either the first state protruding from the side plate or the second state contained within the side plate. The elastic mechanism is disposed within the side plate of the towing body 10 and elastically abuts against the movable baffle 20. The elastic mechanism is used to return the movable baffle 20 to the first state.

[0337] Specifically, the side plate has a chamber. A swing shaft is fixed within the chamber along a first direction. For example, the movable baffle 20 has a wedge-shaped structure, with one end rotatably connected to the swing shaft. An elastic mechanism is provided between the movable baffle 20 and the chamber wall. In the first state, under the action of the elastic mechanism, a portion of the movable baffle 20 protrudes from the side plate, while the other portion lies within the chamber and abuts against the chamber wall, keeping the movable baffle 20 relatively stable.

[0338] The movable baffle 20 can swing (rotate) relative to the swing axis to retract into the chamber under the extrusion force from the side plate perpendicular to it. At this time, the movable baffle 20 is in the second state and the opening 10b is in the open state. After the extrusion force is removed, the movable baffle 20 swings (rotates) in the opposite direction relative to the swing axis under the action of the elastic mechanism to return to the first state and the opening 10b is in the closed state.

[0339] Further optionally, referring to Figures 20 to 22, the movable baffle 20 includes a blocking surface 204 facing the accommodating space 10a and a sliding guide surface 205 facing away from the accommodating space 10a. In the first state, the blocking surface 204 is perpendicular or nearly perpendicular to the first side plate 11.

[0340] In the first state, the sliding guide surface 205 is inclined relative to the blocking surface 204. Further optionally, the sliding guide surface 205 can be a plane or an arc surface. Further, the end of the sliding guide surface 205 near the blocking surface 204 is relatively far from the first side plate 11, and the end of the sliding guide surface 205 far from the blocking surface 204 is close to the first side plate 11. In other words, the movable baffle 20 has a wedge-shaped structure, a triangular block structure, etc.

[0341] When the pool cleaning robot 200 abuts against the sliding guide surface 205 and moves toward the accommodating space 10a, since the sliding guide surface 205 is an inclined surface, the pool cleaning robot 200 abuts against the sliding guide surface 205 and forms a force perpendicular to the first side plate 11, which compresses the first elastic mechanism. Under the compression of the pool cleaning robot 200, the movable baffle 20 swings around the swing axis to the second state, and the opening 10b is in the open state so that the pool cleaning robot 200 can enter the accommodating space 10a.

[0342] After the pool cleaning robot 200 has fully entered the accommodating space 10a, the movable baffle 20 returns to the first state under the action of the elastic mechanism, and the opening 10b is in the closed state.

[0343] When the opening 10b is closed, and the pool cleaning robot 200 abuts against the blocking surface 204, since the blocking surface 204 is nearly perpendicular to the first side plate 11, the pool cleaning robot 200 will not generate a force perpendicular to the first side plate 11 when it abuts against the sliding guide surface 205. Therefore, the movable baffle 20 is in the first state to support the tail end of the pool cleaning robot 200 and prevent the pool cleaning robot 200 from falling out of the accommodating space 10a.

[0344] There can be two movable baffles 20, with the two movable baffles 20 respectively located on the first side plate 11 and the third side plate 13. The above description of the movable baffle 20 is based on the movable baffle 20 located on the first side plate 11. The structure of the movable baffle 20 located on the third side plate 13 and its cooperation with the pool cleaning robot 200 can be found in the relevant description of the movable baffle 20 located on the first side plate 11.

[0345] Referring to Figures 1 to 4, this application also provides a pool cleaning system 2000. The pool cleaning system 2000 includes a pool cleaning robot 200 and a water-removal base station 1000 as described in any embodiment. The pool cleaning robot 200 is disposed within the accommodating space 10a of the towing body 10. The water-removal base station 1000 is used to tow the pool cleaning robot 200 ashore or to send the pool cleaning robot 200 into the pool.

[0346] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application.
